Universal Alarm Bypass Module Models 20402, 23402, 27402 & 29402 This module lets you bypass virtually any type of factory passive anti-theft system on the market today to remotely start your vehicle without permanently disabling the vehicle’s anti-theft system. In 1983, General Motors came out with their first Vehicle AntiTheft System known as VATS which uses a resistor pellet in the key. Since that time, other more sophisticated theft systems have followed. Most of these theft systems are still resistance based, and another uses a “Transponder” which is a tiny pellet or chip embeded within the the head of the ignition key.

Determine which type system you have in your vehicle. If unsure - follow the chart on the previous page to determine the system you have. There are several types of systems as outlined below: General Motors VATS and PASSLOCK 1 and PASSLOCK 2 theft systems. For these, you will be required to dial-in a resistor value which matches the one on your security system. The method is described on the following pages for each type system using the dip switches and the variable resistor. The variable resistor is a 10 turn potentiometer which can be dialed up from zero ohms to 1,000 ohms. SATURN vehicles up to the 2000 model year simply hook up to the Universal Alarm Bypass Module as shown on page 9. If you have a 2000 model year or later Saturn vehicle, see page 10. TRANSPONDER / PASSKEY 3 / P.A.T.S. systems require a transponder (or extra key) to be used with our system. Follow the directions on page 10 and 11.

2. Measure the resistance of the key. It should be between 392 ohms and 11,800 ohms. To do this, put the ohm meter probes on each side of the key pellet. This value should be close to one of the following (all values in ohms): 392, 523, 681, 887, 1.13K, 1.47K, 1.87K, 3.01K, 3.74K, 4.75K, 6.04K, 7.5K, 9.53K, 11.8K. 3. Locate the closest value which is less than your desired value on the chart on page 4. Set dip-switches 2 through 6 as shown on page 4. 4. Put your ohm meter (multi-meter) probes on the two silver resistance measuring pads through the opening shown in the drawing -- making good contact with these two silver pads on the board. (See drawing on page 1). Or put your two probes into the two holes on the bottom of the case making contact with the underside of the silver pads. Either contact point method will work. 5. With the probes held firmly, finish reaching the final resistance value needed for your system by turning the screw on the variable resistor on the side of the unit next to the dip switches. Turn the screw until the resistance value matches the resistance value of the key. 6. Locate the pair of VATS wires (sometimes White/Black striped and Purple/Black striped). These wires are often in a plastic tube. Be careful not to cut into the Yellow Air Bag wires! The Air Bag wires are often in a yellow plastic tube that is clearly marked. The VATS wires run from the ignition switch down the column under the dash. Connect the Universal Alarm Bypass Module using the diagram below.

Put dip switches 1 and 7 in the ON (down) position and dip switch 8 in the OFF (up) position.
2.
Remove the bottom half of the steering column shroud.
3.
Locate the small three wire harness (with White, Black and Yellow wires) running down from the ignition key cylinder on the top right hand side of the steering column into the instrument panel. These wires are usually the smallest wires in the harness.
4.
Cut the Yellow wire in half and strip back both ends. Remove some of the insulation on the Black wire without cutting the wire. The White wire is not used.
5.
Turn the ignition key to the “ON” or “RUN” position and place the vehicle into reverse.
6.
With the ignition key still in and turned to the “RUN” position, measure the resistance between the key side of the Yellow wire (connected to the + positive lead of your digital meter) and the Black wire (connected to the - negative side of your digital meter).

Turn the ignition key to the “START” position and release it. Denote the resistance reading as this will be the resistance that will need to be duplicated. Repeat this step several times to verify that you have a consistent reading. When you have identified the correct resistance use the chart on page 4 to set the resistance on the bypass module. Locate the closest value which is less than your desired value. Set dip-switches 2 through 6 to match the chart on page 4 for this value. Put your ohm meter (multi-meter) probes on the two silver resistance measuring pads through the opening shown in the drawing -- making good contact with these two silver pads on the board. (See drawing on page 1). Or put your two probes into the two holes on the bottom of the case making contact with the underside of the silver pads. Either contact point method will work.
10. With the probes held firmly -- dial-in the final resistance value needed for your system by turning the screw on the variable resistor on the side of the unit next to the dip switches. Turn the screw until the resistance value matches the resistance value of the key. 11. Locate the Black “Bulb Test” wire on the left side of the steering column in cavity “D” or “E” of the Black 5-way connector, just above the main ignition switch connector. This is a different wire than the Black wire mentioned in the above steps. 12. Connect the bypass module using the diagram below. Be sure to tape over any connections to not leave any exposed wires.

To verify the Passlock 1 installation has the correct resistance value and that the installation is correct -- hold the WHITE/ GREEN wire to ground and start the vehicle with the key. If the vehicle starts and stays running - the installation is correct.
PASSLOCK 2: 1. Turn dip switches 1, 7, and 8 to the OFF (up) position. 2. Remove the bottom half of the steering column shroud. 3. Locate the small three wire harness (with Red/White, Yellow and Orange/Black wires on trucks and White, Yellow and Black on cars) that come off the ignition lock cylinder. These are usually the smallest wires. 4. Cut the Yellow wire in half and strip back both ends. Remove the insulation on the Orange/Black wire (trucks) or the Black wire (cars) without cutting the wire. The Red/White or White wire is not used. 5. Turn the key to the “Run” position and place the vehicle in Reverse. 6. Connect the key side of the Yellow wire to the + positive lead of your digital meter and the Black wire (cars) or Orange/Black wire (trucks) to the - negative lead of your digital meter. 7.

8. When you have identified the correct resistance use the chart on page 4 to set the resistance on the bypass module. Locate the closest value which is less than your desired value. Set dip-switches 2 through 6 to match the chart on page 4 with this value.
Saturn vehicles up to the 2000 model year with factory keyless entry have a unique bypass.
9. Put your ohm meter (multi-meter) probes on the two silver resistance measuring pads through the opening shown in the drawing -- making good contact with these two silver pads on the board. (See drawing on page 1). Or put your two probes into the two holes on the bottom of the case making contact with the underside of the silver pads. Either contact point method will work.
2. Locate the Alarm Module behind the right rear quarter trim panel (trunk area). Connect the Pink and Yellow/Black wires of Connector J and D of the alarm module as shown.
1. Set all dip switches to the OFF (up) position.
3. Cut the Pink wire in half and connect as shown.
10. With the probes held firmly -- dial-in the final resistance value needed for your system by turning the screw on the variable resistor on the side of the unit next to the dip switches.

TRANSPONDER / PASSKEY 3 / P.A.T.S.: ‘Smart Key’ & other Transponder systems Note: For this type of security system - you must sacrifice one of the spare keys that comes with the car. This key will be used for the transponder. The dealership can progam a spare key, but make sure they program all keys to the vehicle since learning just one transponder could erase all other key transponders (including the key used for the Bypass Module). 1. Set all dip switches on the bypass module to the OFF (up) position.
4. The transponder LOOP goes underneath the steering column and up toward the ignition key cylinder and needs to be positioned so that there are 2 turns around the ignition key cylinder as shown below. Transponder systems often have a black plastic ring around the ignition lock switch. This is the vehicle’s transponder pick-up antenna. It is important that the two loops of the Bypass Module be mounted on or as close to this black plastic ring as possible. Slide the tube up toward the ignition switch to tighten up the loops of wire. Tape in place to hold. Plug the other end of the transponder loop into the Universal Alarm Bypass Module.
2. Remove the transponder from the key (there maybe a door on the top of the key that can be opened and the transponder can be removed). Or, the entire key may be mounted inside the Bypass Module. Be sure to cut the key in half or grind off some of the teeth to render it unusable. 3. Pull apart the case and place the transponder, or the head of the key, inside the 10 wire loop on the circuit board. Transponders are directional and must be placed along the same direction that the key would lay. Use the double stick foam tape provided -- one layer on the circuit board and then the transponder, or key, and finally the second double-stick foam tape layer on top of it to hold key securly in place. Place Key with Transponder inside case on pc board as shown. Use double stick tape to hold to the key in place.
5. Now start the vehicle with the remote starter. If the vehicle starts and runs for at least 30 seconds the transponder bypass is correct. Note: If the vehicle does not start with the remote starter, try adjusting or changing the position of the transponder in the Bypass Module or adjusting the position of the two loop wire around the transponder pick-up antenna mentioned above.

For Car Starters that do not have an Ignition 3 output: You will need an Ignition 3 output from your remote car starter for all of the hookups shown on the preceding pages. Most models of remote starters use the WHITE/BLACK wire in the control harness as the Ignition 3 output. If you have a brand of remote car starter that does not have an Ignition 3 output -or, if you have an AutoCommand model 20022 or 25522 which do not have an Ignition 3 output -- follow the relay hook-up below using Bosch type 30 Amp relays for creating the Ignition 3 output.
